In this tutorial, you will learn how to delete a failed PHP files upload in a tmp Linux directory. The files are unpredictable that can consume a lot of disk space on the volume.
If you encounter similar to php files below saved on your linux tmp directory that will consume your disk space, you really need to keep track of these files so that your server will not hang up in case you will encounter not enough space on volumes. If ever you are using an Amazon EC2, you can easily to setup a metrics monitoring and alerts for your EBS volumes.
Check out this guide>> to create a resource monitoring for your EC2 instance volume.
However, you’re trying to delete temporary PHP files, but the disk volume still does not decrease, or no changes made?
Similar to this:
Filesystem Size Used Avail Use% Mounted on
udev 468M 0 468M 0% /dev
tmpfs 98M 804K 98M 1% /run
/dev/xvda1 7.7G 7.7G 0 100% /
tmpfs 490M 0 490M 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 490M 0 490M 0% /sys/fs/cgroup
/dev/loop0 94M 94M 0 100% /snap/core/8935
/dev/loop1 94M 94M 0 100% /snap/core/9066
tmpfs 98M 0 98M 0% /run/user/1000
Quick Solution
Therefore, I created a temporary solution using a Bash script to automatically clean up the failed PHP files to save disk space on your root directory volume. The script determines for deleted PHP files to kill those files containing process identification number (PID) older than 5 hours.
To do so, SSH into your remote Linux server and create a new bash file, type command:
sudo vim cleanup.sh
Add the following scripts:
Save and close the file.
Next, make the file executable, type command:
sudo chmod +x cleanup.sh
To execute the file, run command:
./cleanup.sh
Also, You can to assign the script on Cron scheduling job, type command:
crontab -e
Select Vim editor if needed and assign the script at the bottom section, similar to this:
@daily /home/ubuntu/cleanup.sh > /dev/null
Save and close the file.
Next, you can reload the Cron service, type command:
sudo service cron reload
That’s all.
